Embodiment 1

[0026] Embodiment 1: A method for enriching and purifying the volatile oil of Atractylodes atractylodis by using the coupling method of batch distillation-macroporous adsorption resin, the steps are as follows:

[0027] (1) After the dried herb is crushed and passed through a 60-mesh sieve, the dried herb is heated to boiling with purified water according to the ratio of material: water = 1:6, the oil-water mixture is condensed into a distillate and flows out through the condenser, and distilled for 4 hours;

[0028] (2) the herb distillate processed in (1) flows into the oil-water separator for separation;

[0029] (3) Collect the distillate flowing out of the water outlet pipe, carry out double distillation, and distill for 3 hours; collect the volatile oil of Atractylodes atractylodis flowing out from the inlet pipe, combine it with the volatile oil of Atractylodis atractylodis obtained from double distillation, mix evenly, let stand, and suction filter , concentrating unde...

Abstract

The invention relates to a method for enriching and purifying rhizoma atractylodis volatile oil in rhizoma atractylodis by using an intermittent distillation-macroporous absorbent resin coupled method, which belongs to the field of natural organic chemistry. The invention is characterized in that when the intermittent distillation-macroporous absorbent resin coupled method is used for separating and purifying the rhizoma atractylodis volatile oil, the absorption selectivity on the rhizoma atractylodis volatile oil is good, both the absorption and the desorption are fast, the absorption capacity is large, the extraction is convenient and fast, the raw material sources are rich, the production cost is low, the separation effect is obvious, the extraction purity is high, semifinished products of the rhizoma atractylodis volatile oil with the content higher than 35 percent and finished products of the rhizoma atractylodis volatile oil with the content higher than 98 percent can be obtained, and the defects of relatively low extraction rate and low extraction purity of a traditional method are overcome. The invention adopts macroporous absorbent resin with the advantages of stable physicochemical property, large surface area, fast exchange speed, high mechanical strength, strong antipollution capability and good thermal stability, can selectively absorb the rhizoma atractylodis volatile oil from a solution through physical absorption, and has the advantages of fast absorption, fast desorption and large absorption capacity.
